Total = principal * (1 + rate) ^ years
Solving for principal:
principal = total / [(1 + rate) ^ years]
principal = 30,000 / (1.05)^10
principal = 30,000 /

To construct a line perpendicular to line AB and passing through an external point M.
Step 1:- Keep point A as center and draw a circle using compass opened with a width equal to radius AM.
Step 2:- Similarly, Keep point B as center and draw another circle using compass opened with a width equal to radius BM.
Step 3:- The two circles drawn so far would cut at two points, first point is M and second point is N.
Step 4:- Join the two points M and N using straightedge.
Step 5:- Therefore, we have a line MN that is perpendicular to line AB.
Answer: D
Reason: Both of the data shown is in no way symmetric
Angles Q and Q' are congruent, and angles R and R' are congruent.
divide gallons used by time
4 3/8 = 35/8
2 1/2 = 5/2
35/8 / 5/2 = 35/8 * 2/5 = 70/40 = 7/4 (simplest form) = 1 3/4 gallons per hour
